Suppose we know little about the strength of materials but are told that the bending stress in a beam is proportional to the beam half thickness y and also depends on the bending moment m and the beam area moment of inertia i. we also know that, for the particular case m = 2900 in·lbf, y = 1.5 in, and i = 0.4 in4 , the predicted stress is 75 mpa. using this information and dimensional reasoning only, find, to three significant figures, the only possible dimensionally homogeneous formula = y f(m, i).

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
